Abstract: (Elsevier)

The three-body final states Σ ± π ∓ K 0 , Σ 0 π 0 K + and Λπ 0 K +0 produced from πp interactions at 1.69 GeV/ c are examined. The quasi-two-body state Λ(1405)K 0 is discussed in detail. In particular, the spin of Λ(1405) is determined, via the method of Byers and Fenster, to be consistent with 1 2 . The Σ ± π ∓ mass spectrum is compared to that produced by various zero-range and effective-range parametrizations and the Λ(1405) is found to have a mass of 1405 MeV and width of 45–55 MeV. Production and decay characteristics of the quasi-two-body states Σ(1385) 0 K 0 are reported.
